In this two-day lesson, students will be introduced to several water sustainability issues, including access to clean freshwater, groundwater depletion, agricultural water use, and water waste.
On Day 1, students will explore groundwater and how the depletion of groundwater can cause land subsidence in regions like California’s Central Valley. Students will also learn about how agricultural water use for different crops compares to the amount of water required for raising animals on farms and ranches.
On Day 2, students will read some of the Blue Planet Network’s Stories of Water to learn about how different people around the world struggle to have access to clean water and some of the ways they have addressed this issue. They will also explore their own water use habits and ways they can reduce water waste in their home using a water calculator from the Alliance for Water Efficiency and a leaky faucet calculator from the U.S. Geological Survey’s Water Science School.
